Jiangsu PPH Swing Check Valve Manufacturer - Quotation - Processing [Jiangsu Jiayuan Pipe Valve Co., Ltd.] The PPH Swing Check Valve is an automatic valve made of PPH (homopolymers of polypropylene) material, primarily used to prevent reverse flow of medium. Below is a detailed introduction to the PPH Swing Check Valve: PPH Material: PPH is a high molecular weight, low melt flow rate homopolymer of polypropylene, which, after β-modification, features a fine crystalline structure. This provides excellent impact strength and static hydraulic strength at low temperatures, and enhances its resistance to chemicals. Corrosion Resistance: The body, stem, and cover of the PPH Swing Check Valve are all injection-molded from PPH, offering excellent resistance to chemical corrosion and capable of withstanding erosion by various corrosive mediums. High Temperature Resistance: The working temperature of PPH material can reach up to 100°C, making the PPH Swing Check Valve suitable for medium environments with higher temperatures. Non-Toxicity: PPH material is non-toxic and harmless, causing no contamination to the medium, and is suitable for conveying systems in the food and beverage industries.
